Best preamp for Dynaco 70: Tube, SS, or passive?

Well... there is no "best." Lots of tube pres work great. One of the really nice things about 70s is that they are so tweakable and there is a lot of support on the net if you are learning. Are you into DIY at all? I suggest a Bottlehead Foreplay Kit at $150. (www.bottlehead.com).

Lots of great tweaks on a 70 available too. You can upgrade your system without ever leaving home! Check out www.soundvalues.com and Triode Electronics at http://store.yahoo.com/triodeel/index.html

If you have an old Dyno it's great to have a soldering iron.(not brain surgery)

Sincerely, I remain

Gthrush1: that's what I (an old PAS)use in w/ mine! I hesitate to tell folk to use what I do because tastes differ but your right - it's obvious and it works! I use mine in my shop and everytime I listen to it reminds me how far the industry has not come and how much money you do not have to spend to get a musical system. I really think the Dyna is a classic. When I bought my new stuff I could not bear to sell it and I have never regretted that decision.

I remain,
